Poll: What's the next audio breakthrough?

The video guys covering CES 2011 are still trying to pump up excitement about 3D TV, but the audio journalists have nothing to crow about. Yes, I've heard rumors about a new 11.1-channel audio format, but that has even less of a chance of getting any traction in the market than Dolby's rather lame Pro Logic IIz (7.1 height speaker surround format) did a few years ago.

I doubt there's a radical new speaker technology that gets us closer to the sound of live music or home theater bombast coming anytime soon. Portable music players are taking a back seat to smart phones, so I can't imagine any major changes on that front, either.

Of course I could be wrong; what audio breakthroughs do you see on the horizon? Make your suggestions in the Comments section.
